Caught in the Act!

 Dakota Fanning celebrated her sweet 16th birthday with a sophisticated dinner party at Villa Blanca in Beverly Hills. The actress, whose big day is Feb. 23, was joined by 40 guests, including girlfriends from her cheerleading squad and her longtime private teacher. "Dakota looked adorable in a white blouse with a sequined, silver skirt and high heels," an eyewitness tells us. After guests sang "Happy Birthday," Fanning blew out the candles and thanked everyone for joining her for the Mediterranean-inspired dinner. Party guest Cherie Currie – whom Fanning plays in The Runaways – gave the actress a guitar sculpture, which she carved from a solid piece of wood. Says the eyewitness: "She seemed very excited and touched about celebrating her special day with her family and friends."

Later, she returned to the penthouse, where she was staying, and requested bottles of tequila and more champagne.
